The invention relates to a tank for receiving fuel, said tank comprising a venting system comprising a flap for closing an opening made in the tank, said flap being subjected to a float and mounted in a hinged manner in the tank so as to adopt a closed position, pushed by the float when the level of fuel in the tank reaches a certain threshold, and an open, venting position, driven by the float when the level of fuel is below said threshold. According to the invention, the flap comprises a valve controlled by means that can open the valve when the flap is in a closed position and the level of fuel is below said threshold.

A fill limit vent valve for a fuel system includes a housing assembly, an outlet port and a flow dam. The housing assembly has a main housing including a cylindrical body and an upper housing portion. The upper housing portion has a lower wall that defines an orifice and an outer cylindrical wall that defines an upper housing chamber. The outlet port is formed on the main housing and fluidly communicates fuel vapor out of the fill limit valve. The orifice is offset from a centerpoint of the lower wall in a direction away from the outlet port. The flow dam extends from the lower wall into the upper housing chamber and connects on opposite ends to the outer cylindrical wall. The flow dam and upper housing chamber cooperating to form a liquid trap that mitigates the possibility of liquid fuel from reaching the outlet port from the orifice.

A valve assembly includes a valve housing, a cap coupled to the valve housing and defining a cap inlet, a float movably disposed inside the valve housing such that the float is movable relative to the valve housing, a ribbon coupled between the float and the cap such that the ribbon is movable relative to the valve housing upon movement of the float. The float includes a main float body and a retaining feature coupled to the main float body, and the retaining feature secures the ribbon attached to the float.

A shut-off device for a pipe in a pipeline and responsive to ingress of water, has at least two valves for installation in the pipe of the pipeline. Each valve has a valve member supported for movement between an open position when the valve is open for passage of a fluid through the pipe, and a closed position when the valve is closed for preventing passage of the fluid through the valve. The device includes a buoyant member associated with the valve members for causing movement of the valve members to the closed positions upon ingress of water to the buoyant member. The valve members are moved to the closed positions in respective upstream and downstream directions of passage of the fluid through the pipe.

A fuel system includes a fuel tank that has a wall with an opening. A fuel float valve includes a float and a seal plate that are arranged on opposing ends of a beam. A support carries a connection of the beam. The beam is configured to translate along the support at the connection in response to a changing fuel level. The fuel float valve is movable between first and second positions in which the seal plate is respectively unsealed and sealed relative to the opening. The seal plate is movable relative to the opening in the second position.

An active drain liquid trap configured for use with a fuel tank system and constructed in accordance to one example of the present disclosure includes a trap body, a float and a pilot. The trap body defines a first inlet, a second inlet and an outlet. The first inlet is fluidly connected to a fuel pump. The second inlet is fluidly connected to a vapor line. The float is rotatably mounted about a float pivot. The pilot moves between an open and closed position. Rotation of the float causes the pilot to be urged into an open position and fluid to be drained from the trap body through the outlet.

An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir is described. The overfill valve includes a valve body positioned within the drop tube segment and a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. The non-contact valve actuator has a first position in which the non-contact valve actuator does not actuate the valve body from the open position to the closed position in a second position, achieved when the liquid reservoir reaches a predetermined level approaching the capacity of the liquid reservoir, the non-contact valve actuator actuating the valve body from the open position to the closed position when the non-contact valve actuator obtains the second position.

A fuel tank with a venting system includes a flap for closing and opening a vent made in the tank. The flap is coupled to a float. The flap includes a valve coupled to a second float mounted in a hinged manner in the tank so that the valve adopts a closed position, being pushed by the second float when the level of fuel in the tank reaches a certain threshold, and an open venting position in order to prevent overpressure within the tank, being driven by the second float when the level of fuel is below the threshold and the force exerted by the internal pressure on the valve is less than the sum of the forces exerted on the valve by the atmospheric pressure and by the weight of the second float.

A sealing device for an air valve can include a seat; a valve device configured to seal against the seat, the valve device being a poppet and comprising a guide shaft defining a bore extending from the bottom end of the poppet to the top end of the poppet; and a lever arm including a button, removably coupled to the poppet, and configured to engage with and seal the bore of the poppet, the button including a first contacting portion and a second contacting portion.

An overfill valve associated with a drop tube segment fluidly connected to a fluid reservoir is described. The overfill valve includes a valve body positioned within the drop tube segment and a non-contact valve actuator positioned exterior to the drop tube segment and operable to actuate the valve body from an open position to a closed position without requiring any physical penetration through the wall of the drop tube segment. The non-contact valve actuator has a first position in which the non-contact valve actuator does not actuate the valve body from the open position to the closed position in a second position, achieved when the liquid reservoir reaches a predetermined level approaching the capacity of the liquid reservoir, the non-contact valve actuator actuating the valve body from the open position to the closed position when the non-contact valve actuator obtains the second position.
